I had done a sort of off-the-cuff, impromptu site audit a few months ago and one of the people involved with the site sent me a huge box of cookies. I didn't know at the time that she was CEO of a food company. She didn't know that I would tweet and FB about her generosity. Sometimes nice is just... NICE! This is why I love the SEO community - there are so many giving, genuinely nice people.
